Systems and Methods for Authentication Code Entry Using Mobile Electronic Devices

1. A method for authentication code entry, comprising: in a mobile electronic device comprising at least one computer processor, a display, a memory, and an input device: receiving, at the mobile electronic device and from a backend server for an issuer of a financial instrument, a masking pattern that specifies an order of entering digits of an authentication code for the financial instrument into the mobile electronic device, wherein the masking pattern comprises a plurality of placeholders for the digits of the authentication code, and the order of entering digits of the authentication code specifies a first subset of the plurality of placeholders that receive the digits of the authentication code and a second subset of the plurality of placeholders that receive dummy digits; presenting, on the display, a prompt comprising a non-machine readable instruction to enter the digits of the authentication code in accordance with the masking pattern; receiving, at the input device, a masked authentication code entry comprising the digits of the authentication code entered in accordance with the masking pattern and a plurality of dummy digits; storing the masked authentication code entry in the memory; and wirelessly transmitting the stored masked authentication code entry to a point of transaction device as part of a transaction being conducted at the point of transaction device; wherein the backend server is configured to receive the stored masked authentication code entry from the point of transaction device, validate the authentication code using the masking pattern, and communicate the validation to the point of transaction device.

2. The method of claim 1 , wherein the non-machine readable instruction is displayed in a manner such that it cannot be machine-read by an application executed by the mobile electronic device.

3. The method of claim 1 , wherein the stored masked authentication code entry is stored in secure storage of the memory of the mobile electronic device.

4. The method of claim 1 , wherein the non-machine readable instruction is displayed as one or more images.

5. The method of claim 1 , wherein the non-machine readable instruction is displayed as a CAPTCHA.

6. The method of claim 1 , wherein the stored masked authentication code entry is wirelessly transmitted using near field communication.

7. The method of claim 1 , wherein the stored masked authentication code entry is wirelessly transmitted in response to a request from the point of transaction device.

8. The method of claim 1 , wherein the stored masked authentication code entry expires after a predetermined event.

9. A system for authentication code entry, comprising: a backend server comprising a backend computer processor and configured to: generate a masking pattern that specifies an order of entering digits of an authentication code for a financial instrument, the masking pattern comprises a plurality of placeholders for the digits of the authentication code, and the order of entering digits of the authentication code specifies a first subset of the plurality of placeholders that receive the digits of the authentication code and a second subset of the plurality of placeholders that receive dummy digits; and receive a masked authentication code entry from a point of transaction device, validate the authentication code using the masking pattern, and communicate the validation to the point of transaction device; a mobile electronic device comprising a mobile electronic device computer processor, a display, a memory, and an input device and configured to: receive the masking pattern from the backend server; present, on the display, a prompt comprising a non-machine readable instruction to enter the digits of the authentication code in accordance with the masking pattern; receive, from the input device, the masked authentication code entry wherein the masked authentication code entry comprises the digits of the authentication code entered in accordance with the masking pattern, wherein the masked authentication code entry comprises the digits of the authentication code and a plurality of dummy digits; store the masked authentication code entry in the memory; and wirelessly transmit the stored masked authentication code entry to a point of transaction device as part of a transaction.

10. The system of claim 9 , wherein the non-machine readable instruction is displayed in a manner such that it cannot be machine-read by any application executed by the mobile electronic device.

11. The system of claim 9 , wherein the non-machine readable instruction is displayed as a CAPTCHA.

12. The system of claim 9 , wherein the memory comprises secure storage.

13. The system of claim 9 , wherein the non-machine readable instruction is displayed as one or more images.

14. The system of claim 9 , wherein the stored masked authentication code entry is wirelessly transmitted using near field communication.

15. The system of claim 9 , wherein the stored masked authentication code entry is wirelessly transmitted in response to a request from the point of transaction device.

16. The system of claim 9 , wherein the backend server is further configured to expire the stored masked authentication code entry after a predetermined event.

17. A non-transitory computer readable medium having stored thereon software instructions that, when executed by a computer processor in a mobile electronic device, cause the computer processor to execute steps comprising: receive, at the mobile electronic device and from a backend server for an issuer of a financial instrument, a masking pattern that specifies an order of entering digits of an authentication code for the financial instrument into the mobile electronic device, wherein the masking pattern comprises a plurality of placeholders for the digits of the authentication code, and the order of entering digits of the authentication code specifies a first subset of the plurality of placeholders that receive the digits of the authentication code and a second subset of the plurality of placeholders that receive dummy digits; present, on a display of the mobile electronic device, a prompt comprising a non-machine readable instruction to enter the digits of the authentication code in accordance with the masking pattern; receive, from an input device of the mobile electronic device, a masked authentication code entry comprising the digits of the authentication code entered in accordance with the masking pattern and a plurality of dummy digits; store, in a memory of the mobile electronic device, the masked authentication code entry; and wirelessly transmit the stored masked authentication code entry to a point of transaction device as part of a transaction being conducted at the point of transaction device; wherein the backend server is configured to receive the stored masked authentication code entry from the point of transaction device, validate the authentication code using the masking pattern, and communicate the validation to the point of transaction device.

18. The non-transitory computer readable medium of claim 17 , wherein the non-machine readable instruction is displayed in a manner such that it cannot be machine-read by any application executed by the mobile electronic device.

19. The non-transitory computer readable medium of claim 17 , wherein the non-machine readable instruction is displayed as a CAPTCHA.

20. The non-transitory computer readable medium of claim 17 , wherein the non-machine readable instruction is displayed as one or more images.
